Hello. I want to know if pve 7 contains drbd 8 or some other version? (or none)
Last year I upgraded my pve 5 to pve 6 using "in place" and my drbd was broken. I tried hard to fix it but had to give up.
So now I am getting back to this and am thinking I will reinstall pve from an iso. Might as well use pve 7, right?
BTW, drbd 9 never worked for me and I am not too sure what the latest is (Linstor?). I just want good old drbd 8 - it does the trick.
Please don't tell me to use other technology - I just have a small 3 node cluster and the replication is just between 2 of the nodes.
Any advice - should I downgrade to pve 5 or upgrade to 7? I just want the good old drbd.
Also, I don't think I need the "plugin" - I just use the command line.
 
Maybe I should simplify my question? Proxmox is a custom kernel, right? I am just asking what version of drbd is in the latest pve? Is it still drbd 8 I hope?

but we don't ship a storage plugin for DRBD (anymore), and AFAIK the third-party one by linbit is for DRBD9/linstore..
 
both GUI integration and the whole volume management by PVE.
 
But wait, according to the old guide I setup lvm on top of drbd so proxmox just sees lvm right?
 
I am not sure, but in any case, it's not something we support so you'd have to figure out any issues yourself (and I don't think upstream would be much helper either since you are not running their recommended version and tooling).
